O F E,

Josnrn LAURIGH, on SPRINGFIELD, massnonusn'rrsi To all whom it'may concern: 7

Be it known that I, Josnrn LAURICH, a

. subject of the Emperor of Austria-Hungary,

residing in the cit of Sprmgfie' ld' county of Hampden, and Stite of invented certain new and, useful Improvements in Automobile-Hinges, of which the structure, are mounted wit following is a specification.

This invention relates to hinges and more particularly to the so-called concealed hinge.

An object'of. the invention is to provide a concealed hinge which is simple and inexpensive to manufacture.

Another object of the invention is to provide in a hinge of the class described, im-

' proved mechanical structure whereby the hinge is made durable and strong.

Another object is to provide improved :means for attaching the hinge to the door casing.

Other objects and advantages will appear "in the body of the specification and particularly pointed out in the claim. A preferred embodiment of my invention is illustrated in the accompanying drawings in which:

Figure 1. is a plan view of my improved Fig. 2 is a front elevational view.

hinge. thereof. Fig. 3 is a front elevational view of the hinge casing with the hinge structure removed therefrom. Fig. 4 is a plan view of the hinge structure removed from the casing. Fig. 5 is a side elevational' view of the device shown in Fig. .4. Fig. 6 is a sectional plan view on on the line 66 of Fig. 2 and looking in the direction of the arrows. Fig. 7 is a view similar to Fig. 6, showing the parts in an- A casing 2 formed as shown in Figs. 1, 2, and 3 is adapted to receive the hinge structure as a unit. This casing 2 is preferably set into the door casing or wall and secured thereto by screws passing through the flanges 23. The links comprising the hinge 'n a second casing 3, a detail view of which is shown in Fi 4. This casing 3 is adapted to fit closely within the recess21 of the casing 2 and the edges 17 and 18 are arranged to bear against the surfaces 19 and 20. A pair of lugs, 3', which are inte l with the casing 3, are designed to lie wit and closely fit a pair of recesses 2' in the casin 2. A recess 22 in the casing 2 is rqvide to receive the link structure of the iiuge to be described.

sportsman ornate Patent; Application filed 1 .41114, 1014. Serial no. 331,745.

Massachusetts,-,have

an enlarged scale, taken Patented 1, 1914.

It to be ,notedparticularly the structure described forms astrong and sub stantial support .for the hinge and door. The. heavy flangesv 23 extend; considerably above-the casing 2 and allow the latter to be rigidly secured to the walloi' door. casing. The casing 3 fits snugly within the casing 2 and is secured thereto by screws passing through the lugs, 3- Any strain on the hinge structure is transferred directly to the surfaces '19 and 20 of the casing 1. Thus as the casing 2 is rigidly secured to the wall and the casing, 3 is mounted in the closely fitting recess 21, the structure is well adapted to receive any reasonable strain which "may be placed upon'it.

. Fivotally mounted at 8', in lugs 16 in the casing 3, are a number of links 4, as shown four in number are employed. A- second set of links 5 are also pivotally mounted at 9 1n the'lugs l6, and are arrangedin parallel relation. to the links 4. Another set of links 6 are pivotally connected at 10 with the links 4, at 11 with the links 5, and at 12 to lugs 15 which latter are integral with a plate 1.

A fourth set of links 7 are pivotally connected-to the links 5 at a point 13 which lies intermediate the pivots '9 and 11. The other end of the links 7 are connected at 14 to the lugs 15 which, as described, are integral with the plate 1. The plate 1 is a h nge plate and is adapted tobe secured to a door, as indicated at .25 in dotted lines. Fig. 6 shows the position of the parts when the door 25 is in a closed position. All the links4, 5, 6, and 7 lie within the recesses 21 and 22 and are concealed from view. Fig. 7 shows the relative position of parts when the door is fully opened. It will be noted in Fig. 7 that the door 25, notonly has been rotated ninety degrees from the osition shown in Fig. 6, but, has been carr ie a con siderable distance away from the casings 2 and 3. The link 7 serves to prevent rotation of the door 25 onthe pivot 12 which would be possible and undesirable were the pivot 14 removed. Furthermore, this link 7 also constrains the door 25 to move always in a fixed and definite path. Thus, I have 105 provided an improved mechanical structure in a concealed hmge. The structure as a. whole is stron and durable and is attached to the door casing in an improved and eflicient manner. Y 110 It is recognized that many. changes and modifications may be made in the structure above described without departing from the scope of my invention which is more truly defined by the appended claim.

WhatI claim is: a In a hinge, the combination with a casing open at the front side thereof and adapted to be set into a door casing, of a second casing secured to and within said first named casing, a plate adapted to be secured to a door, a set of links having one end thereof pivoted within said second caslng, a second set of links arranged in parallel relation to said first set and having one end pivoted Within said second casing, a .third set of links pivotally connected to said' first and 15 second sets and to said plate, and a fourthset of .links pivotally connected to said second set and to said late, as described.
